We have had some very unusual cool night s for the last 2 nights. The colors of my daylilies have been so dark and rich. I'm giving all the glory to God for making it so cool in June, JUNE!!! The last 2 nights have been like 52 and 54 degrees. We usually have temps in the 70's at night and only dream of a cool night. I love it and my daylilies really really love it!
